Remote Copy failback operation

A failback reverses the manual failover operation and restores the data to a prefailover state. A failback returns the I/O from the secondary location back to the primary location.

For example: you performed a failover to perform testing on the failover system. To restore the original data and not the test data, perform a failback.
NOTE:

If the auto synchronize policy is enabled and you want to restore the original data and not the test data, perform another failover.

A failback operation:

  • Changes the Remote Copy group on the source system back to primary and the target system back to secondary.

  • Provides the host read/write access to the volumes in the Remote Copy group on the source system. The hosts connected to the target system are read-only.

  • Changes the DR state from Failover to Normal.
